[bug#66964] Request for merging "mesa-updates" branch

[John Kehayias]

Hello,

This is to start the process for merging the "mesa-updates" branch. A set of 
commits was just pushed there and the CI already has a build job for this 
branch. It is only 12 commits currently, but will be a lot of builds due mostly 
to the ungrafting of libx11 (and certain package updates beyond mesa itself, 
like pixman, libdrm, etc.). So, mostly waiting for things to build and hoping 
no major breakages. The ungrafts and version updates shouldn't be huge changes 
but you never know.

Please feel free to report any issues here and I'll update as well as things go.

Thanks!
John
